to all sniper users that can not guess what the best sprocket combi that they can use, actually our sniper motor has different power not all are the same specially in stuck, to take the best sprocket combination you must do the trail and error mode, for example try first the 14-40 then 15-38, 15-40, 15-41, 15-42,. all this sprocket combination has different power base on what tire are you using,. I'm using right now is the 15-40 combi, my tires, front 70/80 then 80/80 at my 2nd tire, my top speed was 125 to 130. stuck cdi with port added,.. that's it..,........ drive safe.........

i have a sniper mx and i have stock sprocket of 14-38. i reached 135kph but super yuko na. with brt rcdi. namban r150 bended to fit exhaust. open stock carb and rim tires 60-80 and 70-80 slim. can i reach top easy f i changed sproket at 15-40?

Correct sir. I have been collecting some data here about sprocket combinations. after reaching my top speed at 135kph at my SMX stock sprockets. I reached to conclusion that i can still afford to boost it since i am a 50KG. I reached 140kph just this day after changing sprockets to 15-39 and 428 chains. I have a super slim combination on tires and a rim. stock engine with BRT rcdi. r150 bended to fit Namban exhaust in a stock open carb. This supports your theory sir.
